Input Type: Digital input (dry contact or voltage-based signals)
Number of Input Points: 16 isolated input channels, configured for redundant operation
Input Voltage Range: 24 VDC (typical); supports 19.2 VDC to 30 VDC (operating range)
Input Current: 7 mA maximum per channel at 24 VDC
Isolation: Channel-to-channel isolation (500 VAC RMS for 1 minute); module-to-backplane isolation (1500 VAC RMS for 1 minute)
Response Time: 1 ms maximum for input signal detection
Redundancy Support: Compatible with RX3i system-level redundancy (e.g., dual CPU, redundant backplane) to ensure no data loss during module or component failures
Operating Temperature Range: -25°C to +60°C
Storage Temperature Range: -40°C to +85°C
Relative Humidity: 5% to 95% (non-condensing, per IEC 61131-2)
Certifications: UL 508, CSA C22.2 No. 14, CE (EN 61010-1, EN 61326-1), ATEX (for hazardous locations, where applicable)
Power Consumption: 1.2 W maximum (from RX3i backplane, 5 VDC)
Dual-Redundancy Architecture: The module’s hardware and signal paths are designed with redundancy in mind, enabling it to maintain input signal acquisition if one path or component fails. It works with RX3i’s redundant CPU and backplane to achieve system-wide fault tolerance.
Channel Isolation: Each input channel is electrically isolated from others and the backplane, preventing cross-channel interference and protecting the module from voltage spikes or surges in industrial environments.
Status Monitoring: Integrated LED indicators for each input channel (to show “ON/OFF” status) and module-level status (power, redundancy health) for quick visual troubleshooting.
High Noise Immunity: Complies with EN 61000-6-2 (industrial immunity standards) to resist electromagnetic interference (EMI) and radio frequency interference (RFI), ensuring stable operation in noisy industrial settings.
Hot-Swappable Capability: Supports hot swapping (when used with compatible RX3i backplanes), allowing module replacement without shutting down the entire system—minimizing downtime for maintenance.
Seamless PLC Integration: Configured and monitored via GE’s Proficy Machine Edition software, with built-in diagnostics for fault detection (e.g., open circuits, overvoltage) and easy parameter adjustment.
Application Scenarios
Critical Power Systems: Used in power generation (thermal, hydro, nuclear) and distribution networks to monitor critical input signals (e.g., circuit breaker status, transformer temperature, voltage levels), where downtime could lead to significant losses.
Oil & Gas Industry: Deployed in upstream (drilling rigs) and downstream (refineries, pipelines) operations to track safety-related inputs (e.g., pressure relief valve status, emergency shutdown triggers) and ensure continuous process control.
Chemical & Pharmaceutical Manufacturing: Applied in batch or continuous processes to monitor input signals from sensors (e.g., tank level, flow switches, temperature probes), where process interruptions could compromise product quality or safety.
Transportation Infrastructure: Integrated into rail signaling systems, airport baggage handling, or port container cranes to provide redundant input monitoring, ensuring reliable operation of time-sensitive transportation workflows.
Data Centers & Critical Facilities: Used to monitor power distribution units (PDUs), cooling systems, or fire suppression triggers, where redundant input data ensures rapid response to potential failures that could disrupt critical services.
